# KendoReact setter utility: prototype pollution via controlled field paths

Link for people: https://infrastack.ai/live/CVE-2026-106127 (this .md is for agents)

The setter utility in @progress/kendo-react-common, used by KendoReact versions 3.5.0 through 16.0.0, lets a high-privileged user who controls a field path modify built-in object prototypes. The sources describe the impact as limited to confidentiality, integrity and availability.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of `@progress/kendo-react-common` in your lockfile or with `npm ls @progress/kendo-react-common`
- Confirm whether your app uses KendoReact Form, Scheduler or Gantt with user-controlled field paths

## From the sources

Prototype Pollution in the setter utility (@progress/kendo-react-common) in Progress Software KendoReact versions 3.5.0 through 16.0.0 allows a high-privileged attacker who can control a field path passed to the utility, directly or through components such as the Form, Scheduler, and Gantt, to modify the prototype of built-in objects, resulting in a limited impact on confidentiality, integrity, and availability.
